An exactly solvable model in P.R.M.: quantization. II
Iranzo Fernández, Vicente; Llosa, J; Marqués Truyol, Francisco; Molina, A (1984-01)
Article
Accés obertThe quantization of a priori hamiltonian predictive systems is studied. It is applied to quantize the family of N-particle relativistic models presented in ref. 1. The relativistic two-particle oscillator is studied in ... -
Bifurcations with imperfect SO(2) symmetry and pinning of rotating waves
Marqués Truyol, Francisco; Meseguer Serrano, Álvaro; Lopez, Juan M.; Pacheco, Jose Rafael; López Alonso, José Manuel (2013-04-08)
Article
Accés restringit per política de l'editorialRotating waves are periodic solutions in SO(2) equivariant dynamical systems. Their precession frequency changes with parameters and it may change sign, passing through zero. When this happens, the dynamical system is very ... -
Conductive and convective heat transfer in fluid flows between differentially heated and rotating cylinders
López, José M.; Marqués Truyol, Francisco; Àvila Cañellas, Marc (2015-11-01)
Article
Accés obertThe flow of fluid confined between a heated rotating cylinder and a cooled stationary cylinder is a canonical experiment for the study of heat transfer in engineering. The theoretical treatment of this system is greatly ... -
Confined rotating convection with large Prandtl number: centrifugal effects on wall modes
Curbelo Hernández, Jezabel; López Moscat, Juan Manuel; Mancho Sánchez, Ana María; Marqués Truyol, Francisco (2014-01-23)
Article
Accés obertThermal convection in a rotating cylinder with a radius-to-height aspect ratio of G=4 for fluids with large Prandtl number is studied numerically. Centrifugal buoyancy effects are investigated in a regime where the Coriolis ... -
Crossflow instability of finite Bödewadt flows: transients and spiral waves
López, Juan A.; Marqués Truyol, Francisco; Rubio, Antonio M.; Àvila Cañellas, Marc (2009-11)
Article
Accés obertThe flow in an enclosed rotating cylinder with a stationary lower end wall is investigated numerically. For fast rotation rates, the flow in the interior is primarily in the azimuthal direction, with an angular momentum ... -
Dynamics of axially localized states in Taylor-Couette flows
López Alonso, José Manuel; Marqués Truyol, Francisco (2015-05-15)
Article
Accés obertWe present numerical simulations of the flow confined in a wide gap Taylor-Couette system, with a rotating inner cylinder and variable length-to-gap aspect ratio. A complex experimental bifurcation scenario differing from ... -
Extensional and torsional pipe flow
Marqués Truyol, Francisco; Meseguer Serrano, Álvaro (2019-10-31)
Article
Accés obertWe study the dynamics of a viscous fluid confined within an elastic pipe that is being stretched and twisted in the axial and azimuthal directions, respectively. A comprehensive numerical exploration of self-similar flows ... -
Extensional channel flow revisited: a dynamical systems perspective
Marqués Truyol, Francisco; Meseguer Serrano, Álvaro; Mellibovsky Elstein, Fernando; Weidman, Patrick (2017-06-07)
Article
Accés obertExtensional self-similar flows in a channel are explored numerically for arbitrary stretching–shrinking rates of the confining parallel walls. The present analysis embraces time integrations, and continuations of steady ... -

Flows between orthogonally stretching parallel plates
Ayats López, Roger; Marqués Truyol, Francisco; Meseguer Serrano, Álvaro; Weidman, Patrick (2021-02-01)
Article
Accés obertNavier–Stokes equilibrium solutions of a viscous fluid confined between two infinite parallel plates that can independently stretch or shrink in orthogonal directions are studied. It is assumed that the admissible solutions ... -
Fold-pitchfork bifurcation for maps with Z(2) symmetry in pipe flow
Marqués Truyol, Francisco; Mellibovsky Elstein, Fernando; Meseguer Serrano, Álvaro (2013-07-11)
Article
Accés obertThis study aims to provide a better understanding of recently identified transition scenarios exhibited by traveling wave solutions in pipe flow. This particular family of solutions are invariant under certain reflectional ... -

Impact of centrifugal buoyancy on strato-rotational instability
Lopez Moscat, Juan Manuel; Marqués Truyol, Francisco (2020-05-10)
Article
Accés obertIn a recent experiment on the flow between two concentric cylinders with the inner cylinder rotating and the fluid being stably stratified, Flór et al. (Phys. Fluids, vol. 30, 2018, 084103) found helical wave structures ...
